The Abundant Housing LA Education Fund, a California advocacy group, has announced the winners of the 2025 National Single Stair Architectural Design Competition.
The design competition was meant to showcase innovative single-stair residential building design, a burgeoning housing typology in cities around the country.
Scholar Coby Lefkowitz, architect Gerhard Mayer, and design critic Frances Anderton juried the competition.
Per the competition rules there were three project award categories: Sites were in Austin; San Francisco; and Portland, Oregon.
Single-stair construction is today legal in Austin and Portland, but not San Francisco, where affordable housing advocates are now pushing for single-stair reform.
